WEBHOLDEB GUIDING AND RETAINING DEVICE FOR KNITTING-MACHINES.

Application filed August 10, 1916. serial no. 114,227.

To all whom it may concern:

Be it known that I, Louis N. D. WIL- LTAMS, a citizen of the United States, residing in ()gontz, Pennsylvania, have invented certain Improvements in Web-Holder Guidin and Retaining Devices for Knitting-Machines, of which'the following is a specification.

My invention consists of an improvement in the web holder guiding and retaining devices forming the subject of my Letters Patent No. 1,186,255, dated June (3th, 1916, the object of my present invention being to simplify and c eapen the construction'of the members which alternate with the web holdore and serve to guide the latter in their reciprocating movements and to prevent them from rising under the upward stress of the knitted web upon which they act.

This object I attain in the manner hereinafter set forth, reference being had to the accompanying drawing, in Which Figures 1 to 6 represent difi'erent forms of web holders and guides and retainers therefor inaccordance with my present invention;

Fig. 7 is a perspective'view of that type of web holder shown in Figs. 1, 2 and 3;

Fig. 8 is a perspective view of that type of web holder guide and retainer shown in said figures;

Fig. 9 is a perspective view of that type of web holder guide and retainer shown in Fig. 10 is a perspect ve new of that type of retainer shown in Fig. 5, and

Fig. 11 is an end view of a group of web holders and retainers of the type shown in I n the drawing, 1 represents part of the needle carrier of a knitting machine which,

in the case of a circular knitting machine may be a cylinder or in the case of a straight knitting machine may be a straight bar.

This needle carrier has at the top a head 2 upon which are mounted web holder guiding and'retaining devices consisting of bits 3 each (except in the case of the form shown in Figs. 4 and 9) comprising'a stem or shank 4 with forwardl projecting head 4 at the top and forwar 1y pro ecting tail P at the bottom, the lower portion of the shank and its tail member 4 bein adapted to suitable seats formed in said ead and the upwardly projecting portion of the stem 4 and Specification of Letters Patent.

Patented May 29, 1917.

its forwardly projecting head-serving to fill the space between adjoining web-holders 5 so as to properly guide the latter in their reciprocating movements.

The web holders shown in.Figs. 1, 2, 3 and 7 have formed thereon laterally projecting lugs 6 which are overlapped by the heads 4 of the bits 3, the latter members of the bits thus servin also to prevent rise of the web holders no or the upward thrust imparted to the knitted web by the rising needles. In the construction shown in Figs. 3, 5 and 6, the head 2 has an upper member 2 which is vertically confined to the head by means of any desired number of vertical screw bolts 7, the stems and tail members of the bits being clampedbetween the lower portion of the head and said upper member.

In the construction shownin Figs. 5 and 10 the head member 4 of the bit is downwardly bent and provided with a laterally projecting lug 6 which projects into a slot 8 formed in the web holder and bears upon the top of that member of the web holder below said slot, and in the construction shown in Fig. 6 said downwardly. bent portion of the head member 4 of the bit bears upon a bar 9 which occupies the slot 8 in each web holder and bearsupon the upper" faces of the web holder members below said slot, such her being either in one piece or composed of sections, as desired, and being either straight or circular, depending upon whether the machine is of the straight or circular type.

In that form of guide and retainer shown 6 'which projects into the slot 8 of the web holder is formed upon the stem 4, the head 4* being omitted.

I have found in practice that a needle carrier having a head provided with the bits 3 is preferable, on the ground of economy and facility for making repairs, to a head provided with milled slots for the reception of the web holders, as in my previous patent.

1. The combination of a knitting machine needle carrier with web holders and intervening bits separate from but confined to the needle carrier, said web holders and bits having horizontally engaging members which prevent rise of the web holders.

2. The combination of a knitting machine and retaining bits therefor, separate from but secured to said needle carrier and each comprising an upwardly projecting with projecting tall at the bottom.

3. The combination of a knitting machine needle carrier with web holders and guiding and retaining bits therefor, separate from but secured to said needle carrier and each comprising a stem with forwardly pro'ecting head at the top and projecting tall at the bottom.

4. The combination of a knitting machine needle carrier with web holders and guiding and retaining bits therefor, said bits being separate from butconfined to said needle carrier and having forwardly and downwardly projecting eads which serve as vertical retainers for said Web holders.

5. The combination of a knitting machine needle carrier with slotted .web holders and bits separate from but secured to said needle carrier and having forwardly projecting heads which serve as vertical retainers for those members of the web holders beneath the slots.

6. The combination of a knitting machine needle carrier with slotted web holders and bits separate from but secured to said needle carrier and having forwardly and downwardly projecting heads which serve as vertical retainers for those members of the web holders beneath the slots.

7. The combination of the needle carrier of a knitting machine with slotted web holders and bits separate frombut secured to said needle carrier and having laterally extending lugs thereon which upper faces of the web holder mem rs below said slots.

8. The combination of the needle carrier of a knitting machine with slotted web holders and bits separate from but secured to said needle carrier and having forwardly pro ecting heads with laterally extending lugs thereon which fiuies of the web holder members below said s o s.

9. The combination of the needle carrier of a knitting machine with slotted web holders and bits separate from but secured to said needle carrierand having forwardly and downwardly projecting heads with laterally extending lugs thereon which bear upon the upper faces of the web holder members below said slots.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
